Alexander Graf	0369b2eb07	S390: ccw firmware: Add sclp output ... In order to communicate with the user, we need an I/O mechanism that he can read. Implement SCLP ASCII support, which happens to be the default in the s390 ccw machine. This file is missing read support for now. It can only print messages.

It provides a search for a workable block device, sets it as the default to boot off of and boots from it. Signed-off-by: Alexander Graf <agraf@suse.de>	2013-04-26 20:18:24 +02:00
Alexander Graf	80fea6e893	S390: ccw firmware: Add start assembly ... We want to write most of our code in C, so add a small assembly stub that jumps straight into C code for us to continue booting. Signed-off-by: Alexander Graf <agraf@suse.de>	2013-04-26 20:18:24 +02:00
